To all whom it may concern:

Be it known that 1, JOHN ELMER Gmorr, a citizen of the United States,residing at Mobile, in the county of Mobile and State of Alabama, haveinvented certain new and useful Improvements in Compositions forRemoving Iron Rust From Fabrics, of which the following is aspecification.

This invention relates to compositions of matter, and particularly tocompositions de signed for removing stains of iron rust from fabric.

The general object of my invention is to provide a composition, whichwill hereafter be described, which will remove iron rust stains fromfabric without injuring the most delicate fabric, and which will operateto remove the stains in a very short period of time.

My improved composition consists of:-

Hydrofiuoric acid 1 oz. Borax 5 oz. Distilled water 12 oz.

The ingredients in the above amounts will make approximately one quartof the rust remover. The hydrofluoric acid acts to remove the rust,while the borax cleans the fabric, and the distilled water assists in1'61 leasing or removing the rust without injuring the fabric.

Specification of Letters Patent.

Patented Feb. 15, 1921.

Application filed February 8, 1919. Serial No. 275,892.

lhe fabric which has been stained with iron rust is to be dampened withthe composition and then after allowing a few minutes to elapse for theaction of the composition, the fabric is to be rinsed in clear water,whereupon the iron rust or like spot will immediately disappear and bewashed away; The composition is very cheap and will not injure the mostdelicate fabrics, and has been found to be thoroughly effective inpractice.

I claim 1. A. composition for removing iron rust from fabric, formed bymixing hydrofluoric acid with borax in the presence of water, the boraxbeing in excess of the chemical equivalent in the composition.

2. A composition for removing iron rust from fabric, formed by mixingone part of borax with two parts of hydrofluoric acid in the presence ofwater.

3. A composition for removing iron rust from fabric, formed by mixingtwo parts of hydrofluoric acid with one part of borax in 24 parts ofwater.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses.

JOHN E. GLIOTT.
